Luminescence of trivalent activators in Na3ScSi2O7 host

New results on luminescence in Na3ScSi2O7 are reported. Bi3+ and Ce3+ were chosen as activators. A strong characteristic photoluminescence (PL) originating in transitions from the lowest energy state of 4 fn−15d1 configuration to the ground state of 4 f7/4 f1 configuration was observed for Ce3+. Bi3...

Zusammenfassung:	New results on luminescence in Na3ScSi2O7 are reported. Bi3+ and Ce3+ were chosen as activators. A strong characteristic photoluminescence (PL) originating in transitions from the lowest energy state of 4 fn−15d1 configuration to the ground state of 4 f7/4 f1 configuration was observed for Ce3+. Bi3+ doped sample also showed characteristic emission attributable to 3P 1 → 1So transition.
